Johnny Rutledge is a drifter who comes to and discovers a cabin in the forest where five kids: January, February, March, April, and May are living without parents. Their parents died a while ago, and they want to keep that secret from the townspeople, especially the young school teacher, Prudence Millett, to avoid being sent to a children's home and eventual separation. Johnny moves in with the kids and poses as their uncle to take care of them while romancing Prudence. But in order to keep the children, he has to get married.

Merlin Jones, a precocious and intelligent high-school boy, experiments with hypnosis and creates a mind-reading machine. However, his experiments land him in deep trouble with the law.

Also released as Montana Mike, Heaven Only Knows is an offbeat western with fantasy overtones. Hard-bitten gambling boss Brian Donlevy rules his frontier community with brawn and bullets. To his dismay, Donlevy discovers that he has a guardian angel (Robert Cummings), who shows up in the guise of an Eastern tenderfoot. The angel has been sent from Above to save Donlevy's soul, and to that end encourages the one-time villain to squire a minister's daughter (Jorja Curtwright) rather than his usual dance-hall girls. Donlevy is also given tips on winning against his enemies without resorting to gunplay. The gambler finally redeems himself with Heaven by rescuing the angel from a lynch mob (how can you lynch an angel?) Heaven Only Knows deserves an "E" for Effort for bringing a fresh twist to the venerable western genre.
